Problem with rolling chair

My desk top computer is set up in my living room currently with a regular rolling office chair. My floors are ceramic tiles. The chair is about 2 years old. Recently something appears to be coming off the wheels and leaving black sticky marks on my tiles. I do not want to place any type of mat under this chair as it's in my living room. Now, I am constantly cleaning those marks on the tiles. Any suggestions to put something on those wheels to prevent this?
Any info would be helpful. Thanks.

I have recently bought Sopranos Dvd set and since it's opened, can't return. It doesn't state HDMI or any special player needed. The Dvds roll. No other movies I have do this? What can do, if anything?

Hello,
I recently inherited a chair shown in the following photos:

It is lacquered, with a curved wood back and seat.
